WINDOW-SHUTTER OPENER.

' SPECIFICATION formingpartof Letters Patent No. 270,027, dated January 2, 1883.

Application filed September 6, 1882. (No model.) i

and PETER'J. FINN, both of New Orleans, in the parish of Orleans and State of Louisiana,

have invented anew and Improved Shutter- Opener, of which the following is a full, clear, and exact description.

Theobject of the invention is to provide means whereby the pins which fasten shutters may be drawn out and the shutters thrown open by springs, as hereinafter described.

Reference is to be had to the. accompanying drawings, formiigg part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional elevation of a build ing, showing the arrangement of our improved apparatus. Fig. 2 is a section through the wall, showingthe connection'of the pull devices for being actuated from either outside or Fig. 3 is a detail of a weight contrivance, that maybe employed instead of the spring represented in Figs. 4 and 5, to hold thefasteningdevices 'in position when the sh utters are closed. Fig. 4 isavertical section of a window and shutters; and Fig. 5 is a horizontal section of a pair of shutters, showing the fastening and opening devices.

The shutters a are to be fastened, when shut, by a hasp, b, and pin 0, or any equivalent decord fis attached to a spring, h, or weight 6, at its upper end to hold it up and prevent its weight from tripping the fastenings. .When

it is desirable to extend a branclnj, of thepull device through the wall is of the building to the outside achain will preferably be used, with guide-pulleys lfor it to work on. The shutters are to-be provided with springs m, or equiva lent means, to throw them open instantly when the fastening'pins c are detached.

By the use of suitable guide-pulleys or bellcranks the pull rods or cords may be extended from all sides of a building to one connection, by which all the shutters of a building may be opened at once, whereby labor and time will be saved in opening them daily, and in cases of lireslives and property maysometimes be saved thereby. i

y We may substitute chains and pulleys for the levers e, and in case of need the pull-rings g may be connected to levers, where a large number of fastenings are connected to one pull rod or chain. We propose in practice tojmake the connections so that one shutter of each story may be opened without opening the rest.
